These cookies are crisp on the outside and soft and chewy in the center. Chocolate Chip M&M Cookies These bakery-style massive Chocolate Chip M&M ® Cookies make for such a great treat. They’re soft, chewy, and loaded with chocolate! Plus they’re massive and who doesn’t like huge cookies?! How to make these cookies Combine the butter, brown sugar, and white sugar. Cream the ingredients together; either in a stand mixer or with a hand mixer. Take your time here, because we want the dough to be very creamy and smooth. Add in 2 large egg yolks and the vanilla extract and mix to combine. (Use the extra egg white in this easy egg wrap recipe.) Combine the egg white with cream of tartar. (Here’s a description of what cream of tartar does in baked goods) Beat until light and fluffy. Add the egg mixture to the wet ingredients and fold to combine. Combine all the dry ingredients and stir to combine. Add dry ingredients to wet ingredients. Mix until you’ve got a thick smooth dough. Avoid overmixing the dough; stir until everything is just combined. Add in the regular-sized and miniature chocolate chips. Instructions continued Stir to evenly disperse the chocolate. Measure balls of dough using a 1/4 cup measuring cup to measure the balls of dough. Roll into flat wide discs and press M&M’s on top. Bake! Add a few more chocolate chips and/or M&M’s on top to make these cookies pretty and ensure there is chocolate in every bite of these scrumptious cookies! Chocolate chip M&M cookies baking tips Accurately measure flour: Pushing a measuring cup into a bag or container of flour will pack in way more flour than is needed. To properly measure your flour, spoon the flour into the measuring cup until it’s overfilled. Then use the back of a knife to level the measuring cup at the top. (Video visual here) Room temperature eggs and butter: Don’t melt the butter or the cookie dough will need to be chilled before baking. Check out this guide to bringing eggs and butter quickly to room temperature. Use quality ingredients: Choose real butter (not margarine), pure vanilla extract, and high-quality chocolate chips (I recommend Guittard® or Ghirardelli®) for the best flavor. Use a 1/4-cup measuring cup to get even and consistent dough ball sizes. This will ensure even baking. More cookie recipes: Pumpkin Chocolate Chip Cookies reader favorite recipe!

Course Dessert, Snack Cuisine American Keyword Chocolate Chip M&M Cookies Prep Time 30 minutes Cook Time 12 minutes Total Time 42 minutes Servings 16 large cookies Calories 384kcal Ingredients3/4 cup unsalted butter, at room temperature3/4 cup (133g) light brown sugar, lightly packed1/4 cup + 2 tablespoons white sugar2 large eggs1/2 teaspoon cream of tartar2 teaspoons vanilla extract1/4 teaspoon salt1 teaspoon baking soda2 and 1/4 cups (283g) all-purpose flour Note 12 tablespoons oat flour (oats that have been blended) Note 21 and 1/2 cups (270g) chocolate chips1/2 cup (85g) miniature chocolate chips or chocolate chunks1/2 cup M&M's InstructionsPREP: Preheat the oven to 350 degrees F. Line a large sheet pan with parchment paper or a Silpat liner and set aside.BUTTER AND SUGARS: In a large bowl, beat together the butter, brown sugar, and white sugar until light and creamy, about 3-4 minutes.EGGS: separate the eggs yolks from egg whites (discard ONE of the egg whites or save it for a different recipe -- we only want ONE egg white in this recipe). Beat the egg yolks and vanilla extract into the sugar and butter mixture. Place the remaining ONE egg white in another bowl. Add the cream of tartar in with the single egg white and beat for several minutes until light and fluffy. Add that egg white mixture to the rest of the wet ingredients and mix until combined.DRY INGREDIENTS: In another bowl, mix together the salt, baking soda, flour, and oat flour (Measure the oat flour AFTER blending into a powder and not before. See Note 2 for instructions to make oat flour.) Stir until combined.COMBINE: Combine the dry and wet ingredients and stir until just combined. Stir in the regular chocolate chips, and the miniature chocolate chips or chocolate chunks. We will add the M&M's on top in the next step, not here.COOKIE DOUGH BALLS: Use a 1/4-cup measuring cup to measure out the dough onto a cookie sheet. Strategically place extra chocolate chips and the M&M's on the tops of the cookies. (This way we get a pretty bakery-style appearance.) Roll into big dough balls even in width and height. Place no more than 4 cookies per sheet pan.BAKE: Bake in a fully preheated oven for 10-12 minutes or until the sides are lightly browned. Remove from the oven and allow the heat from the pan to "cook" the cookies on the sheet for about 4-5 minutes before transferring to a cooling rack. Underbaking your cookies is key to soft and chewy cookies. These cookies have a very soft and chewy center with crisp edges. Recipe NotesNote 1: Flour: Accurately measure flour: Pushing the measuring cup into a bag or container of flour will pack in way more flour than is needed. To properly measure your flour, spoon the flour into the measuring cup until it's overfilled. Then use the back of a butter knife to level the measuring cup at the top. (Video visual here) Note 2: Oat flour: If you have quick oats or old-fashioned oats, you'll be set with oat flour in minutes. Here's what you do: Add the old-fashioned oats to a food processor or small blender jar. Pulse the oats until they are ground into a powdery consistency that resembles flour. Stir the oats around to be sure that all the oats have been finely ground and there aren’t any whole oats left (this will affect the texture and liquid absorption of these cookies). Measure AFTER blending and not before.
